Abstract: A method of processing tiled video data by a client device is described wherein the method comprises the steps of: requesting by a client device transmission of video tiles based on the position of a viewport of a display device, the video tiles including at least one or more viewport tiles having a position within the viewport and one or more peripheral tiles, each peripheral tile having a position outside the viewport, the one or more viewport tiles comprising encoded video data of a first resolution and the one or more peripheral tiles comprising encoded data of one or more grayscale semantic segmentation maps; receiving by the client device requested video tiles and metadata associated with the requested video tiles, the metadata including semantic labels for labelling pixel regions in the one or more semantic segmentation maps, wherein the client device is associated with an image synthesis model, preferably an artificial neutral network, which is trained to determine a synthesized peripheral tile of the first resolution based on decoded data of a grayscale semantic segmentation map and semantic labels associated with the grayscale semantic segmentation map; decoding the encoded video data of the one or more viewport tiles into decoded video data of the one or more viewport tiles; and, storing the decoded video data in a decoded playback buffer of a display device associated with the client device for displaying at least part of the one or more viewport tiles in the viewport.
